What I had in mind was to run gated, and have a code on the same box
that endlessly sits in a loop sending queries at regular intervals. If
named does not respond in a specified time interval (open to suggestions
on the time interval), then just assume it is sick and send a SIGTERM
to the pid in /var/run/gated.pid. With BGP the route removal should
be immediate, I'll have to test what OSPF does when a gated neighbor
dies.

I haven't scoured through the bind distribution much but there has to
be some code there I can cannibalize to send queries.
